La-doped BaSnO3 for electromagnetic shielding transparent conductors.

ABSTRACT: In this work, we find that La-doped BaSnO₃ (BLSO) is shown to be a promising electromagnetic shielding transparent conductor. While films grown on industrially practical optoelectronic MgAl₂O₄ substrates have higher sheet resistance by three orders of magnitude than in previous reports, we show how to recover the sheet resistance close to the single-crystal level by use of an MgO template layer which enables high quality (001)-oriented BLSO epitaxial film growth on (001) MgAl₂O₄. There is a positive correlation between crystallinity and conductivity; high crystallinity minimizes scattering of free electrons. By applying this design principle to 5-20% doped films, we find that highly crystalline 5% La-doped BLSO films exhibit low sheet
